Château Calon Ségur

Cabernet Sauvignon is one of the world’s most important and widely planted red wine grapes, renowned for its powerful structure, concentrated fruit and exceptional ageing potential. Originating in Bordeaux, France, the variety has become a defining grape of fine wine regions around the world, particularly Napa Valley, Tuscany, Chile, Australia and South Africa.

Classic Cabernet Sauvignon combines flavours and aromas of blackcurrant, cassis, blackberry and dark cherry with characteristic notes of cedar, graphite, tobacco and herbs. Naturally high tannins and fresh acidity provide structure and longevity, while maturation in oak can add layers of spice, vanilla and toast. Its character varies significantly with climate, soil and winemaking, ranging from elegant and savoury to rich, powerful and intensely concentrated.

In Bordeaux, Cabernet Sauvignon is particularly associated with the Left Bank, where it forms the foundation of many prestigious blends alongside Merlot, Cabernet Franc and other permitted varieties. In Napa Valley, it has become the region’s signature red grape, producing some of the world’s most sought-after Cabernet Sauvignon wines.

Cabernet Sauvignon’s ability to express terroir while retaining its distinctive structure and character has made it a global benchmark for premium red wine. Whether produced as the dominant variety in a blend or as a varietal wine, the finest examples combine concentration, complexity and the capacity to develop gracefully over decades

Merlot is one of the world’s most important red wine grapes, celebrated for its generous fruit, supple texture and ability to produce wines ranging from approachable and elegant to exceptionally complex and long-lived. Originating in Bordeaux, France, Merlot is particularly associated with the Right Bank, where it forms the foundation of many of the prestigious wines of Pomerol and Saint-Émilion.

Merlot typically expresses flavours and aromas of plum, black cherry, blackberry and red fruits, often developing notes of chocolate, tobacco, cedar, herbs and earthy complexity with maturation. Its naturally rounded texture and generally softer tannin profile distinguish it from Cabernet Sauvignon, although the finest examples can possess considerable structure, freshness and ageing potential.

In Pomerol, Merlot reaches some of its most celebrated expressions, particularly on the appellation’s clay-rich soils, producing wines of remarkable concentration, texture and complexity. In Saint-Émilion, it is commonly blended with Cabernet Franc and, to a lesser extent, Cabernet Sauvignon, creating wines that combine ripe fruit with structure, aromatic complexity and longevity.

Beyond Bordeaux, Merlot is widely cultivated in Italy, California, Washington State, Chile and other major wine regions. It can be produced as a varietal wine or used as a central component of blends, where its fruit and texture complement more structured grape varieties.

From the great Merlot-based wines of Bordeaux’s Right Bank to leading expressions around the world, Merlot’s combination of rich fruit, refined texture and capacity to express terroir has established it as one of the defining varieties of fine red wine.

Cabernet Franc is one of France’s most historic red wine grapes, valued for its aromatic intensity, vibrant acidity and ability to express both climate and soil with remarkable clarity. It produces elegant single-varietal wines and plays an essential role in some of Bordeaux’s most distinguished blends. Earlier ripening than Cabernet Sauvignon allows Cabernet Franc to perform particularly well in cooler wine regions.

In the Loire Valley, Cabernet Franc reaches its clearest expression as a varietal wine. Typical aromas include redcurrant, raspberry, red cherry and violet, often accompanied by graphite, dried herbs, tobacco and subtle peppery notes. Naturally fresh acidity and finely structured tannins can produce approachable, fruit-driven wines as well as complex examples capable of developing for many years.

The variety is especially important in Chinon, Bourgueil and Saumur-Champigny. Chinon can range from fragrant and supple to deeply structured and age-worthy, depending on vineyard site and soil. Bourgueil often combines dark red fruit with firm structure, while Saumur-Champigny is renowned for freshness, aromatic purity and refined texture. Limestone-rich tuffeau, gravel, sand and clay all contribute to the diversity of Cabernet Franc across these Loire appellations.

In Bordeaux, Cabernet Franc is principally associated with the Right Bank, particularly Saint-Émilion and Pomerol. Usually blended with Merlot and sometimes Cabernet Sauvignon, it contributes perfume, freshness, savoury complexity and structural precision. On suitable limestone and clay terroirs, Cabernet Franc can become a dominant component of exceptionally refined and long-lived wines.

Beyond France, Cabernet Franc is cultivated in regions including Tuscany, Bolgheri, Napa Valley, Washington State, Canada, Argentina and Chile, producing styles shaped by local climate and terroir. Traditionally known as Breton in the Loire and Bouchet in parts of Bordeaux, Cabernet Franc’s combination of aromatic elegance, freshness and ageing potential establishes it as one of the world’s great red wine varieties.

Petit Verdot is a powerful red wine grape from south-west France, best known as a small but distinctive component of the classic red blends of Bordeaux. Its deeply coloured wines, firm tannins and concentrated aromatics allow even modest proportions to add structure, freshness and intensity alongside Cabernet Sauvignon, Merlot and Cabernet Franc.

On Bordeaux’s Left Bank, Petit Verdot is particularly associated with the gravel soils of the Médoc, including appellations such as Margaux, Saint-Julien, Pauillac and Saint-Estèphe. The variety buds relatively early but ripens late, making complete maturation challenging in cooler vintages. When fully ripe, it can retain vibrant acidity while developing considerable colour, tannin and aromatic complexity.

Typical expressions show blackberry, black cherry, blueberry and plum, accompanied by violet, liquorice, pepper, cocoa and other dark spices. In Bordeaux blends, Petit Verdot is generally used in limited quantities to reinforce colour, tannic structure and aromatic depth. Its combination of acidity and tannin can also contribute significantly to a wine’s ageing potential.

Beyond Bordeaux, warmer and more reliable growing conditions have allowed Petit Verdot to achieve greater ripeness and a more prominent role. Producers in California, Australia, Spain and South America increasingly use the variety in both Bordeaux-style blends and varietal wines. These expressions are often full-bodied and deeply coloured, with ripe dark fruit, floral character, spice and powerful tannins.

From its historic role in the Médoc to its expanding presence as a varietal wine, Petit Verdot is defined by colour, structure, freshness and aromatic intensity. Once regarded primarily as a supporting grape, it is increasingly recognised as a distinctive variety capable of producing serious, age-worthy wines in its own right.
